Wingmirror

I Have a 2000 Focus Zetec 1.8, And recently someone has come along and kicked my wing mirror off, I have found a website that does replacement mirrors but they dont fit them.

I was wondering if anyone could tell me if it was possible to install the mirror myself as I dont want to order it then find out I cant install it, If I can install it myself is it a hard job?, Its not electric by the way,

On the inside of the door where you adjust the mirror, pull back the trim from the front and it should come off. Behind the foam and adjustment wire there is a hole. In the hole is a bolt, use a socket and unbolt this. Once removed the wing mirror should just pull away from the door.

Fitting is just the opposite. Put mirror in place, do up bolt, re-arrange wire & foam, replace trim, done
